Theodoret (Theodoeetus), a Syrian theologian, born at Antioch probably in 393, died in 457 or 458. He was of a noble family, entered a cloister, became in 423 bishop of Cyr-rhus on the Euphrates, and reunited many 'members of the sects with the orthodox church. He declared against the Nestorians, and at the council of Chalcedon, in 451, subscribed the condemnatory decree against Nestorius. He is esteemed as an exegetical writer (see Rich-ter, De Theodoreto Epistolarum Paulinarum Interpreter Leipsic, 1822), and he also wrote homilies, a history of the Christian church from 324 to 429, an epitome of heretical fables, the lives of 30 hermits, and various other works, including 180 letters. Collective editions of his works have been edited by Sirmond (4 vols., Paris, 1642; supplement by Garni er, 1684), and by J. L. Schulze and Nosselt (10 parts, Halle, 1769-74), and in Migne's Patro-logie grecque, vols, xli., xlii., and xliii. A translation of his "Ecclesiastical History" was published in Bohn's "Ecclesiastical Library" (1854).
